TRUCK AND BODY BOLSTER.

SPECIFICATION forming part of Letters Patent No. 738,214, dated September 8, 1903.

Application filed January 24, 1903. Serial No. 140,362. (No model.)

To aZZ whom it may concern.-

Be it known that I, ARTHUR LIPsoHUTZ, a resident of the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Truck and Body Bolsters, of which the following is a specification.

My invention relates to truck and body bolsters for railroad-cars, and the object of my invention is to provide a strong all-metal bolster of less weight and cost than the bolsters which are now in use.

A particular object of my invention is to provide a truck or body bolster or like element in which ordinary rolled or structural steel shapes-such as channel-bars, I-beams, and the like-may be employed without alteration in shape.

My invention consists primarily in a new article of manufacture comprising a pressedsteel truss having a solid web that is rimmed by a flange that follows the complete outline of the truss.

Further, my invent-ion consists in a bolster or other car element, comprising a rolledsteel beam and a truss of the foregoing description, having its long flange riveted to the flange of said beam; and, further, my invention consists in various details of construction and in combinations of parts, all as hereinafter described, and particularly pointed out in the claims.

The invention will be more readily understood by reference to the accompanying drawings, forming a part of this specification, and in which Figure 1 illustrates a car element embody- Fig. 2 is an elevation of a complete bolster. Fig. 3 is an enlarged section on the line as of Fig. 2. Fig. 4 is a section on the line '3 y of Fig. 2, and Fig. 5 is a section showing the element containing an I-beam.

The most practical form of my invention includes a rolled channel 2 or a rolled I-beam 2-3, these being commercial shapes which can be readily obtained in various sizes as required in the manufacture of bolsters or other car elements for cars of different carrying capacities. Other and different beams and shapes may be utilized within the scope of my invention, though not economically adapted to bolster construction. The gist of this invention resides in a pressed-steel individual truss having a continuous flange or rim which is riveted to the flange of the longer beam.

The simple bolster or element of my invention comprises a rolled channel 2, or a rolled I-beani 3, and a shorter truss 4, that is riveted to the lower flange of the beam, with its web 4: in alinement with the web of the beam that is, in the same vertical plane. The truss comprises said web 4: and the continuous flange or rim at, the longest straight portion or side of which is applied to the flange of the beam. As shown, the flange or rim of the truss conforms to the outline of the truss, which, as shown, is of varying depth and is provided with a flat bottom 4!, that isa portion of the flange 4.". In the case of a car bolster the center plate is attached to said flat portion 4. This simple element is suitable for employment as a body-bolster for a light car, and when equipped with columnguides, such as 5, is a very good truck-boL ster for such a car, presenting a maximum of strength in a minimum weight of material. The center bolt7 maypass through the flanges of the beam only or through all the flanges, as shown. A still heavier bolster is made with I-beams 3 in place of the channelbeams. The truck-center 6 may be attached to the top of the truck-bolster or to the bot tom of the truss, if in a body-bolster, in any suitable manner.

It is obvious that numerous modifications of my invention will readily suggest themselves to one skilled in the art, and I therefore do not confine the invention to the specific constructions herein shown and described.

Having thus described -my invention, I claim as new and desire to secure by Letters Patent- 1. The car element, comprising the flanged steel beam, in combination, with the truss provided with a continuous flange or rim, the longest portion of which is riveted to the flange of said beam, substantially as de-' scribed.

2. The car element, comprising the rolled beam of uniform cross-section, in combination, with the pressed-steel truss, comprising a web of varying depth and a continuous flange or rim, the long portion of which is riveted to the flange of said beam, substanand suitable column-guides upon said beam, I0 tiallyes described. substantially as described.

3. The car -bo1ster comprising the rolled Intestimony whereof I have hereunto set beam of uniform cross-section, having a vermy hand this 17th day of January, 1903.
